<?php $arr = array(1,2,3,4,5); foreach($arr as $key => $row) { echo key($arr), '=>', current($arr), "\r\n"; next($arr); } echo key($arr), '=>', current($arr), "\r\n";

Here you find the average performance (time & memory) of each version. A grayed out version indicates it didn't complete successfully (based on exit-code).
